The Effect of KNO3 Compared to KCl on Oxygen Uptake in Heart Failure with Preserved Ejection Fraction
This study is enrolling participants with a diagnosis of heart failure with preserved ejection fraction (HFpEF). This is a condition that causes patients to be short of breath and limited in what they can do in their daily lives. Currently, there are no approved drugs for this condition. Researchers are trying to find new therapies for this condition. The purpose of this study is to test whether Potassium Nitrate (KNO3) will improve how people with HFpEF can exercise. In HFpEF, patients are limited in their ability to do all the things they want to do, and exercise as much as they would like, due to becoming tired and short of breath early. We do not know exactly why these limitations occur. There is some evidence that in addition to problems with the heart, patients with HFpEF also have problems with their arteries and muscles that affect their ability to exercise. Potassium Nitrate has been shown to improve how muscles work and also improve blood flow to working muscles in the body in healthy individuals. We previously conducted a pilot study with our KNO3 pills and found them to be safe in subjects with HFpEF. We would like to now study our pills in a large study to see if we can improve exercise in HFpEF. The use of Potassium Nitrate in this study is investigational. Potassium Nitrate has not been approved by the Food and Drug Administration (FDA) for the use being evaluated in this study

This study will test whether a drug called mavacamten can lower blood levels of cardiac troponin (a marker of heart muscle injury) and/or NT-proBNP (a marker of heart wall stress).
This study is recruiting patients who have been diagnosed with Heart Failure with Preserved Ejection Fraction. The study will test whether a drug called mavacamten can lower blood levels of cardiac troponin (a marker of heart muscle injury) and/or NT-proBNP (a marker of heart wall stress). These “biomarkers” are increased in the blood of some people with HFpEF. Additionally, the main research study will provide preliminary information regarding tolerability and safety of mavacamten treatment in HFpEF. Mavacamten is an investigational drug. This means that it has not been approved by the Food and Drug Administration (FDA) or any regulatory agency for routine clinical use, including the treatment of HFpEF

The BASIC Study: Blood And Sweat chemistry In Cardiology
This study is enrolling patients who have been referred for a treadmill exercise stress test. The purpose of this study is to see if there is a relationship between the chemicals and proteins found in human blood and urine and those found in human sweat. The study will also look to see how the chemicals and proteins in human blood, urine, and sweat may change depending on if a person is at rest or doing a stressful activity such as exercising on a treadmill.
ATTR-CM AI LearningProspective evaluation and validation of an applied ATTR-CM Machine Learning model to a health system electronic health record (EHR)
Prospective evaluation and validation of an applied ATTR-CM Machine Learning model to a health system electronic health record (EHR)
This study is enrolling patients who have a diagnosis of congestive heart failure in their medical record, and is interested in determining whether one can use an automated, computer-based method to diagnose a specific cause of heart failure (“transthyretin cardiac amyloidosis”) based on other diagnoses in the medical record. Transthyretin cardiac amyloidosis is a rare disease that results from a protein in the body that becomes misfolded and starts depositing into the heart, a process known as amyloidosis. Because of these proteins getting into the heart muscle, the heart can get stiff and weak, thereby leading to congestive heart failure. Typically this form of heart disease (cardiac amyloidosis) is diagnosed late in its course and it associated with poor survival. However, there are now treatments for this disease, so earlier diagnosis is better. A machine learning (artificial intelligence)-based method to find potential patients with cardiac amyloidosis has been developed. This computer program automates finding patients who may have cardiac amyloidosis based on their other diagnoses in the electronic health record. This study seeks to validate the computer algorithm prospectively to see if it can be useful in patients to determine whether or not cardiac amyloidosis is the cause of heart failure.
REBALANCE
This study is enrolling patients diagnosed with a form of heart failure that is characterized by a weakened heart muscle that appears to be pumping in a normal manner. This condition is called “heart failure with preserved ejection fraction” or HFpEF. Patient's heart failure is not responding well to the medicine that their doctor has prescribed, and they continue to have symptoms. Their doctor has determined that the health problems and symptoms they are experiencing may be due to a significant increase in the pressure of one of the chambers in the heart. This pressure build-up causes a variety of symptoms, including tiredness, difficulty breathing, and reduced ability to exercise/walk. This study will evaluate a new device (the “Axon System”) designed to reduce the build-up of pressure described above. The relief of this pressure may reduce some or all of the symptoms they are experiencing. The Axon System is not yet approved by the US Food and Drug Administration (FDA) and is considered investigational.
The greater splanchnic nerve (“GSN”) is a nerve that connects to the intestines, liver and spleen. It also communicates with the brain and controls a large volume of the venous blood flow in the body. Researchers believe that in patients with HFpEF the GSN is over-stimulated which causes the body to move more blood into the central veins and lungs. This results in the symptoms experienced, such as shortness of breath with exercise and swelling in the arms or legs. Researchers at Axon decided to study if altering the function of the GSN can improve the symptoms of patients with HFpEF. The purpose of this study is to evaluate the safety and potential benefits of ablation (destruction) of one side of the GSN in patients with HFpEF. Ablation of the GSN is performed for other types of conditions, usually for pain relief in patients with abdominal cancer or chronic pain.
ION-682884-CS2 Cardio-TTRansformTransthyretin-mediated amyloid cardiomyopathy (ATTR-CM), which is a disease caused by change in a protein called transthyretin (TTR).
Transthyretin-mediated amyloid cardiomyopathy (ATTR-CM), which is a disease caused by change in a protein called transthyretin (TTR).
This study is enrolling patients who have transthyretin-mediated amyloid cardiomyopathy (ATTR-CM) which is a disease caused by change in a protein called transthyretin (TTR). This change can either be sporadic which is known as wild-type (wtATTR-CM) or due to a mutation of the TTR gene which is hereditary (hATTR-CM). In both cases, these changes can cause the TTR to clump and build up in certain parts of the body such as the nervous system, stomach, intestines, and heart. This build up is called an amyloid deposit. Amyloid deposits can sometimes cause heart disease or neuropathy (nerve damage). When amyloid is deposited into the heart, it can result in a condition referred to as cardiomyopathy. ION-682884 is an investigational drug. “Investigational” means that ION-682884 is not yet approved for use in any settings outside of clinical research studies like this one and is considered experimental. ION-682884 reduces the level of TTR in the blood of animals and healthy volunteers tested to date. Reducing the amount of TTR in the blood may reduce the amount of amyloid deposits in the body and may keep cardiomyopathy from getting worse over time. However, it is not known if ION-682884 will help cardiomyopathy. The purpose of this study is to evaluate the safety of ION-682884 and determine if it can help people with this type of cardiomyopathy.
Polydiuretic in HFpEFHistory of heart failure with preserved ejection fraction and diabetes mellitus
History of heart failure with preserved ejection fraction and diabetes mellitus
This study is enrolling patients at Northwestern Memorial Hospital with a history of heart failure with preserved ejection fraction and diabetes mellitus. Doctors at Northwestern University want to better understand if combining three different types of medicines at low doses into one pill can simplify and improve treatment for people who are prone to retaining fluid because of a condition called heart failure with preserved ejection fraction. Specifically, this is the most common type of heart failure and occurs with a normal ejection fraction or squeezing capacity of the heart muscle. Because patients with diabetes mellitus and heart failure with preserved ejection fraction are more likely to retain fluid, we are studying people with both of these conditions. The medicines being used in this study - bumetanide, eplerenone, and dapagliflozin- are all approved by the Food and Drug Administration (FDA) and commonly prescribed by medical providers for heart failure with preserved ejection fraction (bumetanide and eplerenone) and diabetes mellitus (dapagliflozin). In this study, they will be combined into one pill, a “Low-Dose Triple Polydiuretic Therapy” or “LDTPT” to see if LDTPT leads to reduction in NT-proBNP, a hormone which is high among persons who have heart failure with preserved ejection fraction. The (FDA) has not approved the LDTPT pill for general use and its use in this study is experimental.

HAPI-HFHAPI-HF Study: pHysiological signals, Activity and Posture for surface mounted Insertable Cardiac Monitor in Heart Failure
HAPI-HF Study: pHysiological signals, Activity and Posture for surface mounted Insertable Cardiac Monitor in Heart Failure
This study is enrolling patients to use a wearable insertable cardiac monitor to better understand the various sounds that the heart makes during cardiac tests. You are being asked to participate in this study because Boston Scientific Corporation (BSC) is making a device called the insertable cardiac monitor (ICM) that measures certain heart functions. The device also works when it is placed on top of the chest. BSC made a more comfortable, wearable version of the device to use in this study. The wearable device is called the wearable cardiac monitor (WCM). As part of the study, the WCM will collect data during tests while taped to the skin. The tests include leg raise exercises, lying down, sitting and/or standing, and an optional submaximal exercise test for participants the study doctor determines appropriate. There may also be an echocardiogram during these tests. An echocardiogram takes pictures of the heart using sounds waves created by the heart. The purpose of this study is to collect data during a series of tests to see if the WCM can detect signals related to heart failure. This data will be compared to the data obtained by the echocardiogram.

PRESERVED-HFEffects of dapagliflozin on biomarkers, symptoms and functional status in patients with type 2 diabetes or pre-diabetes, and preserved ejection fraction heart failure (PRESERVED-HF Trial)
Effects of dapagliflozin on biomarkers, symptoms and functional status in patients with type 2 diabetes or pre-diabetes, and preserved ejection fraction heart failure (PRESERVED-HF Trial)
This study is enrolling patient who have heart failure (inability of the heart to pump blood with normal efficiency).The purpose of this study is to find out if a drug called dapagliflozin would be effective in improving the blood tests and symptoms related to your heart failure. To do this, dapagliflozin will be compared with placebo. The placebo is a pill that will look like dapagliflozin but will not have active ingredients. Dapagliflozin lowers glucose (sugar) levels in the blood by blocking the effect of specific molecules (small particles) in the body called sodium-glucose transporters. Under normal circumstances, the sodium-glucose transporters in the kidney prevent glucose in your blood stream from leaving the body through urine. Dapagliflozin inhibits the sodium-glucose transporters and lowers the blood glucose by allowing glucose removal through the urine. Dapagliflozin may also mildly decrease body weight and lower blood pressure in certain patients. Decreasing body weight and lowering blood pressure may improve the blood tests and symptoms related to heart failure.
